vANTI-FRICTIONAL BEARING.

SPECIFICATION forming part of Letterslatent No. 258,042, dated May 16, 1882.

Application filed March 15, 1882. (No model.)

.To all whom tt may concern Be it known that I, THoMAs R. FERRALL a citizen of the United States, residing at Boston,in the county of Suffolkand State of Massachusetts, have invented certain new and useful Improvements in Anti-Frictional Bearings; and I do hereby declare that the same are fully described in the following specification and illustrated in the accompanying drawings.

This invention relates to improvements in anti-frictional bearings; and it is carried out as follows, reference being had to the accompanying drawings, on which- Figure 1 represents a side elevation of the improved anti-frictional bearing. Fig. 2 represeiits a vertical section, and Fig. 3 represents a cross-section, of the same. Fig. etrepresents a side elevation of a modification of the invention. Fig. 5 represents a vertical section, and Fig. 6 represents a cross-section, of the said modification.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

aa represent the case or shells within which the anti-frictional rollers b b b are located, each such case or shell being provided with an inwardly-projecting annular iiange, a', to prevent a longitudinal motion of the rollers b'b b the rollers b b at a proper distance apart, andA within said case a a.

cc are the regulators, one at each end of the rollers b b b, which regulators are provided with inwardly-projecting dividers c c', (shown in Fig. 2,) one between each pair of successive rollers b b, which projections serve to keep to prevent their coming in contact with each other.

d 'd are rivets uniting the two regulators c c, and serve to hold them together at a proper distance apart, according to the length ot' the rollers b b, as shown in Figs. 1, 2, and 3.

c is the central bearing-sleeve, with outwardly-projecting annular viianges e e in its extreme ends, so as to prevent it from moving "longitudinally, for which purpose said anges e' e pass by a portion of the ends ofthe rollers b b, as shown in Fig.' 3.

c" is the central cylindrical bored-out hole, for the reception of the spindle or axle for which the anti-frictional bearing is intended, such bored-out hole being preferably provided with annular groove or recess 0', adapted to contain lubricating material.

Figs. 4, 5, and 6 show a modication of the invention, in which the dividers c c c are dispensed with, instead of which the regulators c care provided with cylindrical projections c c, tting into corresponding cylindrical recesses inthe ends of the-rollers b b, as shown in Fig. 6. Another modification is the removalof the annular anges c' c of the eentral bearing-sleeve, e, which latter is made in the modication as cylindrical, (shownin Fig. 6,) and the regulators c c are each provided with an inwardly-projecting annular lip, c4, which projects over each end of the central bearing-sleeve, c, as shown in Fig. 6, so as to prevent said bearing-sleeve from longitudinal motion in the direction of its axis.

This improved anti-frictional bearin g is very simple in its construction. It is composed of very'feW parts, which are very easily put together in making the improved bearing, and permanently retained in working positions in a very practical and durable manner.

What I wish to secure by Letters Patent, and claim, is

In an anti-friction bearing, the combination of the shells or cases a, having anges a', the revolving sleevebearing e, the series of rollers b, the regulators c, the connecting pins or rivets d, and the annular anges e', or their described equivalents, coacting with the parts specified to prevent the sleeve-bearing from moving longitudinally in the direction of the axis of the shaft,.substantially as described.

2. The herein-described anti-frictional bear ing, consisting of the case or shells a a, their annular anges a a', the rollers b b,- the regulators c c, with their rivets d d d and dividers c c', and the central bearing-sleeve,c, with its .lianges c e', said anges c coacting with the parts specified to prevent the sleeve-'bearing from moving longitudinally in the direction of the axis of the shaft, all constructed, arranged, and combined as and for the purpose set forth.

In testimony whereof I have affixed my sig` nature in presence of two witnesses.

THOMAS R. FERRALL.
